Cyclone nossles. — The cyclone nozzle is the prototype of the Ver- 

 morel. It discharges the spray at right angles to the axis of the 

 pipe which leads to the nozzle. Stahl's cyclone is shown in Fig. 12 

 and Myers' Hop Nozzle, a cluster cyclone, in Fig. 13. By some these 

 nozzles with side discharge are considered specially desirable for 

 spraying low plants and the under sides of foliage, but as a matter 

 of fact they are not superior to the Vermorel. 



Cluster nozzles. — A group of nozzles supplied by one lead of hose 

 is called a " cluster." By means of suitable attachments these clusters 

 may include two or more nozzles. Other things being equal this in- 

 crease in the number of nozzles attached to one lead of hose increases 

 the area which may be covered by one workman in a given period 

 of time. Some of the best and most experienced managers of spray- 

 ing outfits hold the opinion that with good apparatus and good pres- 

 sure it is not economical to include more than two Vermorel nozzles 

 in a cluster. A double Vermorel is shown in Fig. 8 and triple and 

 quadruple forms in Figs. 9 and 10. In some clusters Vermorel 

 nozzles are used to give a very fine spray carrying but a short dis- 

 tance while adjustable nozzles at the same time throw a coarser and 

 farther reaching spray. 



Nozzle accessories. — Various kinds of nozzle attachments are 

 offered, as Y's, strainers or separators, shut-off discharge connec- 

 tions and devices by which the spray may be driven at any angle 

 to reach any surface. 



The Loop separator. — This is a strainer which is attached to the 

 discharge pipe of the tank for the purpose of separating from the 

 liquid any particles which might clog the nozzle. See Fig 14. It 

 consists of a brass cup separated into two chambers by a disc of wire 

 cloth. The liquid enters the lower chamber, passes through the wire 

 cloth to the upper chamber from wliich it is discharged into the hose 

 leading to the nozzle. In the bottom of the cup is an orifice which 

 may be opened at will for cleaning the chamber of sediment. This
